Description
DETERGENT COMPOSITIONS
TECHNICAL FIELD
The present invention relates to detergent compositions or components thereof containing cationic surfactant and a colorant fixing agent. Generally, the detergent compositions of the invention are for use in laundry washing processes.
BACUND OF THE INVENTION
It is known how to use cationic surfactants in detergent compositions. For example, GB 2040990A discloses granular detergent compositions comprising cationic surfactants. It is also known to incorporate cationic dye fixative polyamine agents in detergent compositions, as described in EP-A-462806. However, formulations containing such polyamines exhibit poor stain removal properties, since they tend to coat the surfaces of the fabric thus trapping any stain on the surface of the fabric. The use of anionic surfactants to solve this problem can promote dye fading. Applicants have found that this problem can be reduced by using a cationic surfactant in combination with cationic dye fixative polyamine agents. Further, it is considered that after the cleavage of any oily dirt caused by the enzyme, the cationic surfactants used in the present invention can complex with the fatty acids and any other negatively charged product produced by the cleavage, increasing their solubility and increasing the removal of dirt from grease and oil and the general cleaning action, before the deposition of the coloring fixing agents. All documents cited in the present description are incorporated herein by reference.
BRIEF DESCRIPTION OF THE INVENTION
The present invention relates to a detergent composition or component thereof comprising: a) a dye fixing cationic agent; and b) a cationic surfactant of formula I:
R1R2R3R4N + X "
Wherein R1 is a hydroxyalkyl group having not more than 6 carbon atoms; each of R2 and R3 is independently selected from C? -4 alkyl or alkenyl; R4 is an alkyl or alkenyl of C5-? 8; and X "is a counterion.
As used herein, unless otherwise indicated, alkyl or alkenyl may be branched, linear or substituted. The substituents may be, for example, aromatic groups, heterocyclic groups containing one or more N, S, O atoms, or halogen substituents.

In an aspect of the invention, the average particle size of the components of the granulated compositions according to the invention should preferably be such that no more than 15% of the particles are more than 1.8 mm in diameter and not more than 15% of the particles are less than 0.25 mm in diameter. Preferably, the average particle size is such that 10% to 50% of the particles have a particle size of 0.2 mm to 0.7 mm in diameter.
The term "average particle size" as defined herein is calculated by sieving a sample of the composition in a number of fractions (typically 5 fractions) in a series of sieves, preferably Tyler sieves. The fractions of weight thus obtained are plotted against the opening size of the sieves. The average particle size is considered the size of the opening through which 50% by weight of the sample would pass. In a further aspect of the invention, at least 80%, preferably at least 90% by weight of the composition comprises particles with an average particle size of at least 0.8 mm, most preferably at least 1.0 mm and more preferably 1.0, or 1.5 to 2.5 mm, More preferably at least 95% of the particles will have said average particle size. Said particles are preferably prepared by an extrusion process. The overall density of the granular detergent compositions according to the present invention is typically an overall density of at least 400, preferably 600 g / liter, most preferably from 650 g / liter to 1200 g / liter. The overall density is measured by means of a simple funnel-cup device consisting of a conical funnel rigidly molded on a base and provided with a butterfly valve at its lower end to allow the contents of the funnel to be emptied into a cylindrical cup aligned axially below the funnel. The funnel is 130 mm high and has internal diameters of 130 mm and 40 mm in its respective upper and lower extremities. It is mounted in such a way that the lower extremity is 140 mm above the upper surface of the base. The cup has a total height of 90 mm, an internal height of 87 mm and an internal diameter of 84 mm. Its nominal volume is 500 ml. To carry out a measurement, the funnel is filled with manually poured dust, the butterfly valve is opened and the powder is allowed to overfill the cup. The full cup is removed from the frame and the excess powder is removed from the cup by passing a straight edge implement, eg, a knife, through its upper edge. The full cup is then weighed and the value obtained for the weight of the powder is doubled to provide a global density in g / liter. Equal measurements are made as required. The compacted solids can be manufactured using any suitable compaction process, such as rattling, agglomeration or extrusion, preferably tableting. Preferably, the tablets that will be used in dishwashing procedures are manufactured using a normal rotary clack press and using compression forces of 5 to 13
KN / cm2, very preferably from 5 to 11 KN / cm2 so that the compacted solid has a minimum hardness of 176N to 275N, preferably 195N to 245N, measured by a C100 hardness test as provided by I. Holland instruments. This method can be used to prepare homogeneous or stratified tablets of any size or shape. Preferably, the tablets are symmetrical to ensure uniform dissolution of the tablet in the wash solution.
Laundry Washing Method The laundry washing methods of the present invention typically comprise treating the laundry with an aqueous washing solution in a washing machine having dissolved or supplied therein an effective amount of a laundry detergent composition in accordance with the present invention. with the invention For an effective amount of the detergent composition it is tried to say from 10g to 300g of product dissolved or dispersed in a washing solution of a volume of 5 to 65 liters, which are typical doses of product and in volumes of washing solution commonly used in conventional laundry washing methods. The dosage depends on the particular conditions such as water hardness and degree of soiling of the laundry. The detergent composition of the invention can be brought into contact with the fabric to be treated in a washing step or in a rinsing step.
The detergent composition can be supplied, for example, from the assortment box of a washing machine or it can be put in contact with the fabric to be treated in the machine. In one aspect of use, a delivery device is employed in the washing method. The delivery device is loaded with the detergent product and used to introduce the product directly into the drum of the washing machine before starting the washing cycle. Its volume capacity must be such that it is capable of containing sufficient detergent product that would normally be used in the washing method.
The delivery device containing the detergent product is placed inside the drum before the start of the washing cycle, before, simultaneously with or after the washing machine has been loaded with clothes. At the beginning of the washing cycle of the washing machine, water is introduced into the drum and it rotates periodically. The design of the delivery device must be such as to allow the dry detergent product to be contained but then allow this product to be released during the wash cycle in response to its agitation when the drum is turned and also as a result of its contact with the washing liquid. To allow the release of the detergent product during washing, the device may possess a number of openings through which the product can pass. Alternatively, the device may be made of a material that is liquid permeable but impermeable to the solid product, which will allow the dissolved product to be released. Preferably, the detergent product will be released rapidly at the start of the wash cycle, thereby providing transient localized concentrations of the product in the drum of the washing machine at this stage of the wash cycle. The preferred delivery devices are reusable and are designed in such a way that the integrity of the container is maintained both in the dry state and during the wash cycle. Especially preferred delivery devices for use with the composition of the invention have been described in the following patents: GB-B-2,157,717, GB-B-2,157,718, EP-A-0201376, EP-A-0288345 and EP-A- 0288346.
